The Subseasonal-to-Seasonal (S2S) Prediction Project is a joint undertaking by WCRP and WWRP which completed its first phase between 2013 and 2017. Last week, the Project's Phase I Final Report has been officially published, reporting on the period from November 2013 to December 2017. The report can be downloaded from WCRP's publications page. The S2S Prediction Project aims to improve forecast skill and understanding on the S2S timescale with special emphasis on high-impact weather events. Its full scope is laid out on the S2S Prediction Project homepage as well as on WCRP's S2S webpage. The proposal for the S2S Prediction Project's Phase II can be downloaded from the S2S homepage.
